Chain Corpay One actions in LangChain

Feed your agent a list of tools like `list_payments` or `list_financial_documents` and watch it build a logic path. The output from one call flows into the next without you needing to write manual glue code. Tracing every step in LangSmith shows you exactly how the agent decides to hit the API. You’ll see the latency and the specific arguments passed to `create_new_document` in real time.

Automate vendor management via MCP

Use `list_account_vendors` to get your supplier list directly into your LangChain agent's context. It makes mapping invoices to specific entities instant. Your agent can cross-reference these vendors against incoming documents. It handles the lookup before you even have to glance at the dashboard.

Trace payment data flows

Every tool call is a node in your chain, allowing you to debug how Corpay One data moves through your app. If a `get_payment_details` call fails, you see the exact input that caused the issue. This visibility matters when you're building complex pipelines. You aren't guessing why a payment didn't process; you're looking at the stack trace.

Setup guide

Set up Corpay One MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes Corpay One tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "corpay-one-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent Corpay One transactions"
    })
    print(result["messages"][-1].content)
